The Model 3019 is an ergonomically-designed, low-weight digital background survey meter used for background measurements of gamma radiation levels up to 500 µSv/hr (50 mR/hr). An internally installed Csl scintillator provides 175 cpm per µR/hr sensitivity. This instrument’s alarm set points can be designated through Setup Mode using the onboard keypad, or alternatively by USB connection via the optional software. (See Options tab, Lumic Calibration Kit - Part Number 4498-1018.)

Other features include a large, easily-readable LCD (liquid crystal display); an audio warning tone; and easy, intuitive design. Splash-resistant construction matched with a housing made of durable, high-impact plastic enables this instrument to be used indoors or outdoors. The padded handle is shipped pre-configured for datalogging operations with the built-in logging push button and warning light, making the device ready if the customer chooses to acquire the optional datalog software (Lumic Datalogging Kit - Part Number 4498-1019, includes software and required cable).

Operators can access several setting adjustments, including calibration constant, dead time correction, efficiency, high voltage, high voltage current overload level, pulse threshold, response time (fast or slow), count time, operational modes (Rate, Max, or Count), and minimum and maximum display levels. The user may also set Primary and Secondary units, unit alarm levels, count units, count alarm levels, and zero pulse protection time limit. Zero pulse protection will warn the operator by causing a zero reading to flash and triggering an audible alarm after a user-selected number of seconds with no pulses from the detector. Another alarm, the sigma audio feature, assists search efforts by issuing an audible alarm when radiation levels outside set parameters are detected. An internal switch is used to enable or disable the front-panel setup feature to protect desired settings from inadvertent modification.

The Model 3019 is shipped ready to use, with batteries and calibration certificate.
